CNC Machining Services in China

Are Precision CNC Machining Services Suitable for Industry? A CNC-based precision machining system is a great choice for manufacturing today because the design of CNC precision machining is conducive to modern manufacturing. We live in an age in which there is "custom" production. In the China the past, the majority of the manufacturing process was driven by high-production and a lack of focus on modifying the final product. However, the majority of manufacturing today is focused on a greater degree of customization. The Tuofa Precision CNC machining manufacturer This design philosophy demands an extreme amount of flexibility. The Precision CNC Machining process is engineered to provide higher precision and repeatability and shorter setups, short lead times, shorter inventoriesand complicated fixing. This kind of CNC Machining Services is utilized to manufacture components that are used in almost every modern market. It's also a great fit for the application of

Application of high precision CNC engraving service High precision CNC engraving is good at small tool finishing, with the ability of milling, grinding, drilling, and high-speed tapping, and is widely used in the 3C industry, mold industry, medical industry, and other fields. This article collects frequently asked questions about CNC engraving. 1. What is the main difference between high precision CNC engraving and CNC milling? Both high precision CNC engraving and CNC milling use the milling principle. The main difference is in the diameter of the tool used. The commonly used tool diameter range for CNC milling is 6-40 mm, while the tool diameter for CNC engraving is 0.2-3 mm. 2. Is CNC milling only for rough machining and high precision CNC engraving for finishing? Before answering this question, let's first understand the concept of process. The amount of machining in the roughing process is large, and the amount of finishing machining is small. Some people h

A must-have manual for CNC! 1. knife point The tool position point is a reference point on the tool, and the trajectory of the relative movement of the tool position point is the processing route, also called the programming trajectory. 2. Knife setting and setting point Tool setting means that the operator makes the tool position coincide with the tool setting point through a certain measurement method before starting the NC program. You can use the tool setter to set the tool, its operation is relatively simple, and the measurement data is relatively accurate. After positioning the fixture and installing the parts on the CNC machine tool, you can use the gauge block, feeler gauge, dial indicator, etc., and use the coordinates on the CNC machine tool to set the tool. For the operator, it is very important to determine the tool setting point, which will directly affect the machining accuracy of the part and the accuracy of program control. In the batch production process

6 important points of positioning parts of CNC lathe The processing technology of CNC lathes is similar to ordinary lathes. Still, CNC lathes are one-time clamping, and all turning processes are completed automatically and continuously, so the following aspects should be paid attention to: 1. Reasonable cutting Reasonable selection of cutting allowances Whether the selection of cutting allowances (ap, f, v) is reasonable plays a very important role in whether the potential of the machine tool and the cutting performance of the tool can be fully utilized and the realization of high quality, high yield, low cost and safe operation is very important. When rough turning, first consider selecting a larger back-cut amount ap, secondly choose a larger feed amount f, and finally determine a suitable cutting speed v. Increasing the back engagement amount ap can reduce the number of tool passes, increasing the feed rate f is conducive to chip breaking. Therefore, selecting the amo

Metal precision machining refers to some small diameter of the metal parts for processing, precision metal processing of materials, design drawings, etc., are important, so in precision metal processing, some matters need attention. Otherwise, it may cause the product a phenomenon such as a scrap; so what does precision hardware processing need to pay attention to?   Matters needing attention in precision hardware machining:     1, Needing accurate design drawings   Because precision hardware processing is to process some small diameter hardware parts, the design drawings must be accurate; if the drawings are not accurate, parts are a mile away, which may lead the parts not to be used, thus improving the production cost.   2, the material of metal  precision machining   The product of precision hardware processes is normally used in aviation, clock, and so on. which is highly required in material quality. So high-quality materials are generally used in precis

Stamping is a forming and processing method that relies on press and mold to exert an external force on a plate, strip, pipe, and profile to produce a plastic deformation or separation to obtain the required shape and size of the workpiece (stamping). Sheet Metal Stamping Parts Characteristics   Compared with castings and forgings, with thin, uniform, light, and strong characteristics. Stamping can increase rigidity by producing parts with stiffeners, ribs, undulations, or flanges that would otherwise be difficult to produce. Due to the use of a precision die, workpiece accuracy can reach micron level, and high repetition accuracy, consistent specifications, can be stamped out of the hole, boss, etc... a Stamping machine, cold stamping parts generally no longer by cutting or only need a small amount of cutting. The precision and surface state of hot stamping parts is lower than that of cold stamping, but they are still better than castings and forgings. Stamping is an efficient

1. Precision Machining Shaft Parts 1) Dimensional accuracy, the journal is the main surface of shaft parts, which affects the rotation accuracy and the working state of the shaft. The diameter accuracy of the journal is usually IT6 ~ 9 according to its use requirements, and the precision journal can reach IT5. 2) Geometric accuracy, journal geometric accuracy (roundness, cylindricity), generally should be limited to the diameter tolerance point range. When the accuracy of a geometric shape is required to be higher, the allowable tolerance can be specified on the part drawing separately. 3) In The machining position, the accuracy mainly refers to the coaxiality of the matching journal of the assembly transmission parts relative to the supporting journal of the assembly bearing, which is expressed by the radial circular runout of the matching journal to the supporting journal; According to the use requirements, the high precision axis is 0.001 ~ 0.005mm , and the general preci

The processing method of the surface of the CNC machined part first depends on the technical requirements of the machined surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing. Sometimes, they may be higher than the requirements on the part drawing in some respects due to technological reasons. For example, due to the misalignment of the benchmarks, the processing requirements for the surface of some CNC workpieces are increased. Or, because it is used as a precision benchmark, it may put forward higher processing requirements. When the technical requirements of the surface of each CNC machined part are clarified, the final processing method that can guarantee the requirements can be selected accordingly, and can determined processing methods of several working steps and each working step. The selected machining method of CNC parts should meet the requirements of parts quality, good machining econ

To meet the design accuracy requirements of the parts, the processing sequence arrangement should follow certain principles. 1) Rough first, fine later The processing sequence of each surface is roughing, semi-finishing, finishing and finishing to gradually improve the precision and surface quality of the machined surface of parts. Suppose CNC machine tools process all the surfaces of the parts. In that case, the working procedure is generally arranged in the order of roughing, semi-finishing, and finishing. That is, the roughing is completed and then semi-finishing and finishing. Roughing can quickly remove most of the machining allowance and then finish each surface, in turn, to improve production efficiency and ensure the machining accuracy and surface roughness of parts. This method is suitable for machining surfaces with high position accuracy. This is not absolute, such as for some higher dimensional accuracy requirements of the machining surface, taking into accoun
